FILLING-CARRIER FOR wnr'r-nnrnnnismne Looms.

Patented Sept.- 14, 1909.

Application filed October 10, 1 908. SeriaI No. 457,118.

To all whom it mdy concern; Be 1t known that we, JoHN R. FITTON andCris-units H. BERGLUND, a citizen of the in Filling-Carriers. for\Vett-Replenishing Looms, of which the following is a specification.

' Our invention relates to a filling carrier or shuttle for weft.replenishing looms, in which a new filling carrier or bobbin isautomatic ally inserted when the filling carrier-or bobbin in therunning shuttle is substantially or practically exhausted, and ourinvention more particularly relates to a. self-tl reading shuttle,having an automatic'filling thread cutting mechanism combined therewith,of the type shown and described in the Letters l atent of the UnitedStates, No. 914,703.

The object of our ,invention is to improve upon and simplify theconstruction of the self-threading cutting mechanism shown and describedin said Letters Patent, and also to. provide an improved selftl1rea-dingmechan ism for the shuttlef In the self-threading shuttle shown anddescribed in said'Letters Patent, a filling carrier or bobbin, havingfirst wound thereon a few winds of filling in one direction, and the remaining winds of filling in the reverse dimotion, is used. li -hen newfilling is inserted in the shuttle from the weft replenishi ingmechanism, the filling is automatically threaded into the eye of'theshuttle by the threading mechanism, and as't'he filling is drawn offfrom the bobbin, it is carried by 1 its circular nwrement into. a guide,and remains in said guide until the fillin .on the bcibbin, of theordinary wind, has" een en- 5 tirely draw-n off from the bobbin, andthe? filling of the reverse wind is reached; the-n by reason-ofthereverse wind of the filling, the filling is caused. to have acircular movement in an opposite direction, and passes out 1 of theguide referred to. and into another guide or eye in a position to beengaged by the cutting mechanism to be out at the next operation of saidcuttingmechanism, al lfias fully described in said Letters Patent.

In our improvements, we do away w-itlr the funnel-shaped guide, shownand de scribed in said patent, for the filling, and" ordinary wind. anupward direction, and is provided with substitute therefor a' double, orlooped wire, over which the filling thread freely passes, as long as thefilling on the bobbin has the An arm or lever extends in an eye at itsupper end, from which a slightly curved slot extends downward y, whichslot open at its lower end, and adapted to have the filling pass intoit, when the filling, wound in the ordinary way, has been entirely drawnoil from the bobbin, and the filling having the reverse wind, isreached.

Our self-threading mechanism, which we hate combined with. our presentimprove ments in filling cutting mechanism, is of very sii'npleconstruction, and consists of a suitably shaped metal plate, having ahorn or hook on one end, and a downwardly extending portion, adapted toguide'thefilling,

and to hold it in the thread. eye.

'We have only shown in thedrawing a detached portion of a shuttle withour iml proveinen-ts combined therewith, sufiicient to enable thoseskilled in the art to understand the construction and operation thereof.

Referring to the drawing':Figure l is a plan View of one end of ashuttle, and our improvements in thread cutting mechai'iisin, and aself-threading mechanism, attached thereto; the fillin is shown as it isdrawn otl' from the bobbin in the usual or normal direction. Fig. 2corresponds to Fig. 1, but

shows the self-threading mechanism removed, and the filling thread drawnoft from the bobbin in the reverse direction, to be cut by the cuttingmechanism.

Ablock AL is suitably secured in a recessed portion of the'back wall oftire shuttle, and is. in this instance similar to the block shown anddescribed in said with a, filling thread eye 6'.

.up and "4 has on .its upper end a cam-shaped plate Letters Patent, No.91et,703. The block l has in thisinstan ce two :inwardly verticallyextendlng progections'i, one of which is provid d on its upper edgewitha cutting sur- 'lac 1".". Extending through the lower part ot. thepro ections l 1s a pin 5, on which lower end, and adapted to receive thefilling 3 on llS circular movement upwardly and.

toward the cutting lever, as shown in Fig. 2, when the filling isunwound from the bobbin in a reverse direction from the ordinary wind.The lever 6 has a rearwardly extending arm 6 which extends through ,anopenii'ig 7 in a bolt 7,wl1ich,extends loosely in an. opening in theblock l, tohave a vertical down movement therein. The bolt or head 7",which isadapted to be engaged and'operated by a trip, not 'shown,suitabl'y located on the hand-rail of the loom, or, the

head 7" shuttle box, not shown. A helically coiled expansion spring. 8,extends between the onthe bolt 7, and, the upper part of the bearing inthe plate t for the bolt 7, and

acts to-yieldin-gly move up the bolt 7 and the arm 6" on' the lever 6,to hold said lever lll'ltS inoperative position, as shown in. Fig.

4:. The engagement of theend of the arm- 6" of the lever 6, with theupper part of the.

transverse opening through the block 4,

limits the upward movement of the bolt 7, see Fig. l.

, Extending out from the two projections 4 on the block 4:, and in thisinstance attached thereto, is a double wired}, preferably of loop shape,which forms aguide for the filling 3,

which loosely passes over said wire as long asthe filling is unwoundfrom the bobbin 111 the ordlnary (llI'BCt-IOH, as shown in Fig. 1.

\Ve will now describe our improvements.

in the self-threading mechanism shown in the drawing.- Theself-threading mechanism consists in this instance of a' top plate 10,preferably made of sheet metal, which jection 10.

extends upon the upper side of the shuttle, as shown in Fig. 1, and hasextending downwardly therefrom in a vertical plane and at right anglesthereto, and preferably riveted thereto, a second plate or projection.10, see Fig. 5, which extends in a recess 1" in the shuttle 1, and issecured therein, in this instance by a screw 11 extending through anopening 10 in the pro- The inner edge of the plate 10 is preferably madeof curved shape, as shown in Fig. 1. and at the outer end of said placeof'the practical plate is a horn or hook 16, around which,

the thread passes, and is guided along the inclined e'dge-' 10 on theprojection 10",

see Fig. 6, and through the curved thread slot 1 ii: the side of theshuttle l, 'and into 'theopen ye 10 in the projection 10",.and

into the thread eye 1- in the shuttle. The vertically extending plate orprojection 10' on the plate 10 has secured thereto, or made integraltherewith, a side plate 10 which extends inwardly into the opening inthe body plate or projection 10 is preferably of the shape shown inFig.7, and has on its edge,

near its upper end a notch or undercut p0r-' U011 10", which acts tohold the filling in the proper position as it is being threaded into theshuttle.

7 From' the above description in connection with'the drawing, theoperation of our im provementswill be' readily understood by thoseskilled in the art. 7 f The filling carrier or bobbin to be used in ourimproved self threading shuttle, as stated above, has the filling woundthereon of the shuttle,- preferably. .at right angles to the plate 10,see Fig. 4, The side.

asthe shuttle is thrown through the shed,

it will have a circular movement, and when a full bobbin is' transferredfrom the magazine into the running y or substantially exhaustedbobbin ithe shuttle, the. end of the filling on the bob in being attached to asta azine, the filling. is. drawn into the threading mechanism, and.

tionary part of the ma automatically threaded into the jshuttle',as theshuttle is thrown across the lay from the magazine end thereof. Theunwinding-of -the filling-from the bobbin,- as-the shuttle is operated,communicates to'the fillinga circular "movement. away? from the cutting-n1echanism,asshown in Fig. 1,,and the loop wire v9 acts as support forthe filling.

at a predetermined time, the cutter lever 6 will be moved toward therear side of the shuttle, to carry the filling against the cutting edgeat on one of the projecv block 4, 'and clit the filling,
